This 1989 Jeep Grand Wagoneer was built by Black Mountain Jeep in Wylie, Texas. The company replaced the factory 360 ci (5.9 L) AMC V8 with a supercharged 6.2 L Hellcat V8 crate motor making 707 hp and 645 lb-ft of torque. They installed the engine using custom mounts, rear sump oil pan, and Grand Cherokee Trackhawk exhaust manifolds. Behind the V8 sits a Chrysler 727 three-speed automatic transmission rebuilt with a Jeep main shaft. This allowed the luxury SUV to retain the Jeep transfer case and four-wheel drive.

Love this. The Grand Wagoneer is one of my favorite vehicles. Finding a good survivor is tough these days. They all practically came pre-rusted from the factory. Would have been nice if they put an OD transmission in it. Can’t imagine that getting better than single digit fuel mileage.
